📦 Creating volume from existing image, attaching and mounting

📌 Introduction​

This guide describes the process of:

  • Creating a volume from an image
  • Attaching the volume to a Nuvion VM
  • Validating and mounting the volume in the operating system

This process is useful for:

  • Cloning systems
  • Environment recovery
  • Distribution of pre-configured data

⚠️ Points of attention​

  • The volume may already contain partitions (e.g., /dev/vdb1)
  • Do not format (mkfs) if data needs to be preserved
  • The device name may vary (vdb, vdc, etc.)
  • Always validate with lsblk

🔧 Steps​

1️⃣ Create volume from an existing image​

  • Access the panel and click on Images
  • Click the three dots (...) of the desired image
  • Then, click Create volume

  • Choose the size (GiB)
  • Select the Storage Policy (disk type)
  • Click Create

✅ Confirm creation​

  • Wait for the success message

2️⃣ Attach volume to Nuvion VM​

  • Access the Volumes menu
  • Locate the created volume (Example)
  • Click the three dots (...)
  • Select Attach

👉 Select Nuvion VM​

  • Choose the desired Nuvion machine
  • Click Done

3️⃣ Access the Nuvion VM​

  • Access Virtual Machines
  • Click the three dots (...)
  • Select Console

ℹ️ A new window will open in your browser with the console screen of your Nuvion VM.

4️⃣ Validate disk in the system​

Run:

lsblk

👉 The new disk will appear as /dev/vdb (or similar)

5️⃣ Create mount point​

➜ Create a directory where you want to mount this volume

mkdir -p /meusistema

imagem

6️⃣ Identify filesystem (optional)​

blkid /dev/vdb1
info

Useful to check:
Type (ext4, xfs)
UUID

➜ Do not format (mkfs) if data needs to be preserved

imagem

7️⃣ Mount the volume​

mount /dev/vdb1 /meusistema

imagem

8️⃣ Validate mounting​

df -h
info

The volume should appear mounted in the configured directory

💡 Best practices​

  • Use UUID in /etc/fstab for persistence
  • Validate permissions after mounting
  • Monitor usage with df -h
  • Avoid overwriting volumes with data

🎯 Summary​

In this process, we create a volume from an existing image, attach it to a Nuvion, and perform its mounting in the operating system, allowing secure and controlled access to the data.
